Names

There are so many names that I just think about and wonder about them. On this post, we can just discuss different names. I know it sounds weird, but I have a first query of my own, and I think you'll see what i'm getting at.

When I say Brittany, I say it like Britt-knee even though it's not really spelled that way. I know it's probably just american slang got to it, but does anybody say it as Britt-a-ny? Also, why do we say Britt-knee and not Tiff-knee but rather Tiff-a-ny(thats how i pron. it anyways) as its spelled. Sorry if this looks confusing how i wrote it. but its just a query.
